The cover and its panels are fit the mattress in a manner to secure the cover on the mattress against edgewise movement, it being understood that forgcertain types of sofa beds one or both of the side panels 34 may be extended to the floor.

A number of sofa bed accessories generally indicated by the reference numeral 31 are shown in Fig. 1 positioned upon a rear edge portion of.

the covered mattress of the bed structure in such a manner as to provide a continuous back rest extending between the end members If! and ll of the structure. As indicated inFig. 2 the length of the sofa bed is twice its width dimension whereby a single rest 31 may be disposed adjacent an end member IQ thus forming with the bed structure a comfortable chaise longue, whendesirable.

With reference to Figs. 3 and 4 each back rest has a bolster or back part 38 constructed from a plurality'cf horizontally acting inner springs 39 having their end coils secured able links 43 to provide a resilient, form retaining body for the bolster. The springs are covered by a layer of padding 4! which in turn is enclosed in ticking 42. The padding 4| may be made of cotton felt or a combination of sisal and cotton or suitable foamed rubber, and the like. The unit so formed of resilient cushioning material provides-a relatively medium resistance to pressure and has a relatively dense, form retaining characteristic brought about principally by the action of the inner springs. The form of the bolster is substantially trapezoidal in lateral section, said unit having a fiat base 43 and a front wall 44 inclined upwardly and rearwardly from the frontedge of the base. i

The usual head pillow 45, substantially ovoid in section and in its usual pillow case, serves as a soft, pliable forepart 46 for the back rest. As indicated in Fig. 3 said pillow is divided into three or more compartments by cross webs 47, each of the compartments formed by the webs being filled with a soft material such as feathers, hair or other suitable material such as foam rubber, or the like. This compartmented pillow is particularly advantageous for my purposes because it confines the soft material in suitable layers within the pillow cover and precludes collection of all the said material at the bottom edge, whereby said pillow will retain its ovoid shape in use either as a back rest or as a bed head rest.

With reference to Fig. 3 a case 48 encloses the bolster part 38 and. the forepart 46 of the aceessory and is adapted to maintain said parts in cooperative juxtaposition when the accessory is used as a back rest. The case comprises two compartments 49 and 50, each made of fabric upholstering material and 52 respectively; and in this respect it is particularly pointed out that that portion of the upholstery material 52 which covers the base 43 of the bolster part has a rough face for purposes to be more fully described hereinafter. The compartment 50 is constructed to snugly enclose the bolster 3B, the case for said compartment having an elongated opening 53 therein for removal of the bolster therefrom, it

together by suit-- thereforetailored to j usual manner.

in operative positions by longitudinal lines of a being contemplated that said opening may be closed by overlapping flaps, suitable button fastenors, hookless fasteners 54, or the like (Fig. 4). The other cover compartment 49 is substantially ovoid in section and is also constructed with an elongated opening 55, said opening being closed by a hookless fastener 56, or the like in the The compartments are secured stitches 51' (Fig. 3) which pass through the upper portions only of the material forming the compartments 49 and 5B for the back rest parts.

As shown in Fig. 5 I contemplate enclosing the forepart pillow 45 and the back part bolster 38 in a single case 58, said case having a normally closed, elongated opening 59 therein for removing one or both of the parts when desired.

It is to be understood that the spring group 23 for the bed structure has a special row 23 and of highly tempered, strong springs along its front and back edges to give additional support to the superjacent edges of the mattress. As illustrated in Fig. 3 the row of back rests 37 are supported upon the rear edge of the mattress above the reenforced row of springs to maintain the back rests against undesirable depressive movement when the device is used as a sofa. It

7 will also be appreciated that the front row 29 of reenforced springs will effect a stronger support for the users legs than the center of the bed structure thereby easing the user into a comfortable sitting position with his back firmly pressed into contact with the rest.

It will be noted also that the front wall 44 of the bolster part 38 for my accessory is inclined with respect to its base 43 and that the bolster has a form retaining characteristic that is lacking in the softer forepart attached to the front wall. When a users back is supported by my rest the greater component of his reclining weight is directed by the bolster front wall downwardly upon the base of the bolster, and the base in turn forces the upholstering material 52 covering said base into frictional contact with the mattress cover 33. As has been specified both the said cover 33 and at least the bottom of the case 58 for the bolster part are constructed from upholstery material having rough facings. The interengagement of the facings of the said cover and case bottom. together with the downward force exerted on the bolster when it is in operative back supporting condition provides an elfective means for precluding rearward sliding movement of the accessory that stabilizes the acces sory on the bed structure as a secure and comfortable back rest. It is also pointed out that the side and end panels for the mattress cover in no small measure assist in providing a practical back rest for my sofa bed in that the cover is thereby positioned on the mattress against edgewise movement.

When it becomes necessary to use the sofa illustrated in Fig. 1 or the chaise longue shown in Fig. 2 as a bed it is only necessary to remove the accessories 31 from the structure, and then remove the head pillows 45 therefrom through closures 55 provided in the accessory cases illustrated in Figs. 1-4 inclusive or through closure 59 when the accessory shown in Fig. 5 is used upon the bed structure. The cover 33 is then taken off the mattress 3i which would preferably expose a fully made-up mattress complete with bed clothing 32. By placing at the head of the bed one or more pillows 45 removed from the accessories the bed structure is immediately available for sleeping purposes.

What is claimed is:

1. In a sofa bed the combination of a frame, a box spring assembly extending above the frame at least along the front and rear edges thereof, a mattress upon the spring assembly, means for reenforcing that portion of the spring assembly along the front and rear edges of the, mattress, a fabric mattress cover having a comparatively rough facing, means for removably securing the cover on the mattress against edgewise movement, and a number of back rests disposed in a row upon the back edge portion of the covered mattress and each rest comprising a resilient and relatively dense, form retaining bolster part having a fiat, stabilizing bottom wall, a soft, pliable forepart for the bolster, and a fabric case enclosing the parts and maintaining said parts in fixed relative positions, said case having a comparatively rough facing on at least its bottom wall in frictional contact with the back edge portion of the said mattress cover for maintainin the bolster part in position upon the back edge portion of the covered mattress.
